Abstract (en)

[origin: WO2017144605A1] A digital-to-analog converter comprises a converter output (11), a dummy output (12), a first number N of current sources (13 -17), a first switching arrangement (18), a first current divider (24), a second switching arrangement (31) and a second current divider (60). The current sources (13 -17) are coupled via the first switching arrangement (18) to the converter output (11), the dummy output (12) or to an input current terminal (25) of the first current divider (24). The output current terminals (26 -30) of the first current divider (24) are coupled via the second switching arrangement (31) to the converter output (11), the dummy output (12) or to an input current terminal (61) of the second current divider (60).The output current terminals (63 -66) of the second current divider (60) are coupled to the converter output (11) or the dummy output (12).
